Abstract: A particulate filter and method of manufacture. The particulate filter includes intersecting walls that define longitudinally extending channels The intersecting walls comprise a porous ceramic material having a bare microstructure that comprises an interconnected network of porous spheroidal ceramic beads that has an open intrabead porosity within the beads and an interbead porosity defined by interstices between the beads. Catalyst particles are deposited at least partially within the intrabead porosity within the interbead porosity. The bare microstructure has a bimodal pore size distribution in which an intrabead median pore size of the intrabead porosity is less than an interbead median pore size of the interbead porosity. The filter has a trimodal pore size distribution comprising a first peak corresponding to the interbead porosity, a second peak corresponding to the intrabead porosity, and a third peak corresponding to the intrabead porosity as blocked by the catalyst particles.

Abstract: An inkjet printhead, a system including an inject printhead, and a method for applying primer to a target area on an outer surface of a ceramic body. The inkjet printhead comprises an ink chamber comprising the primer therein. The primer comprises a pigment, a binder, and a solvent. The primer also comprises a surface tension of at least about 40 mN/m. A spray nozzle is connected to the ink chamber and comprises an exit opening that comprises an area of less than about 20,000 square microns. The spray nozzle is configured to eject droplets of the primer from the exit opening at an average exit velocity of less than about 4 m/s.
